You are pushing 170 in and getting 150 or so or more out? So it is possible that the air that blows adross the steel fins is not being directed properly, or the cores fins have dirt or an issue keeping the exchange from taking place. Next step is to pull the controls and see, if you can, if it has a cable that is ok, or not ok.
Then you can see where it(called a blend door) is and if it is moving prperly. Ok
Do you understand? The water is hot going in, and hot coming out, so the cable and door inside are the next things to look at.
It is more of a door moving properly issue now.
